I think that everyone has an equal chance, regardless of what guild they're in. It's obvious that by being in those guilds, the people hiring are more likely to know your personality and who you are(if you're in the same guild). But that doesn't mean they're more likely to get in. They have to write an application like everyone else - and have an equal chance of getting rejected. I'm not a fan of recommendations though. This is my opinion. I could be completely wrong. XD
But I do agree about the applications though. But if it works for iClassic, why not. I think it would be better if the situational questions were asked in an interview; the person is more likely to have to think on the spot.
